Turkey's outgoing premier Recep Tayyip Erdogan was Thursday sworn in as president as opponents who accuse him of authoritarianism after more than a decade in power walked out of the ceremony.
Erdogan, 60, took the oath in Ankara to begin a five-year mandate in which he has vowed to build a "new Turkey" by pushing through a new constitution and driving on with an ambitious development programme.
Deputies of the opposition Republican People's Party (CHP), who accuse Erdogan of violating the constitution, noisily walked out of parliament just before he was sworn in.
Erdogan has made clear he wants to wield genuine executive power as president after becoming the first directly elected head of state, taking 52 percent of the vote in the August 10 poll.
His recent predecessors in the Cankaya presidential palace performed a largely ceremonial role.
The election was a triumph for Erdogan -- who first become premier in 2003 -- after surviving a tumultuous 2013 that saw mass anti-government protests and corruption allegations against his inner circle.
He will take over as president from Abdullah Gul, a former close comrade and co-founder of the ruling Justice and Development Party (AKP), who appears now to have fallen out with the feisty Erdogan and is expected to play no role in the next government.
- Western leaders stay away -
Heads of state from a dozen nations in Eastern Europe, Africa, Central Asia and the Middle East attended the ceremony, the Anatolia news agency reported.
But leaders of top Western states were conspicuous by their absence in a possible sign of suspicion towards Erdogan's strongman tendencies.
The United States is only sending its charge d'affaires in Ankara, in what some commentators have seen as a clear snub.
Ukraine's President Petro Poroshenko had to cancel his trip due to the advance of pro-Russian forces in the east of his country.
A man clearly with his eye on history, Erdogan's five-year presidential term means he will have ruled Turkey longer than its modern founder Mustafa Kemal Ataturk, who established the republic out of the ruins of the Ottoman Empire.
He can serve two mandates and so could theoretically stay in power until 2024, which would allow him to see in the 100th anniversary of modern Turkey in 2023, and portray himself as a historic figure to rival Ataturk.
"The birthday of a new Turkey," headlined the staunchly pro-Erdogan Yeni Safak daily.   
Erdogan has made clear he wants to press on with a mind-boggling programme of infrastructure projects including a mammoth new airport in Istanbul, a new canal to divert shipping from the Bosphorus and a high-speed rail network for the whole country.
- 'Above the law' -
Taking his oath of office, Erdogan swore to "abide by the Constitution, the rule of law, democracy, the principles and reforms of Ataturk, the principles of the secular Republic."
But opponents have accused Erdogan of seeking to undermine Ataturk's legacy with authoritarian tendencies and imposing a creeping Islamisation of society.
Controversially, he wants parliament to change the constitution after the 2015 legislative election to invest the presidency with more powers.
"We are faced with a man who places himself above the law and does not abide by any rule. But this kind of mentality is unacceptable," said CHP leader Kemal Kilicdaroglu.
Under Turkish law, the president should sever all ties with political parties -- but Kilicdaroglu said Erdogan had no intention of distancing himself from the AKP.
"This is a clear attack on the state's honour and dignity," said Kilicdaroglu.
Taking over Erdogan's post of prime minister is Foreign Minister Ahmet Davutoglu, 55, a long standing ally who is expected to do little to challenge the Turkish number one.
Davutoglu was confirmed as party leader Wednesday at a vast meeting of the AKP at which both men vowed there would be no change in policy, despite the changeover.
"Names change today but our essence, our mission, our spirits, our goals and ideals remain in place," Erdogan told the meeting.
Davutoglu will form a new cabinet by Friday, with intense speculation over who will hold the top jobs, with the head of Turkey's intelligence service Hakan Fidan a possible new foreign minister.
Davutoglu, who became foreign minister in 2009, is a controversial figure blamed by some for pursuing an over-ambitious foreign policy that led to the rise of Islamic militants in Syria.
